You have a Cisco Unified Border Element configured to provide H.323 to SIP interworking. Which

command will verify that you have a single H.323 and a single SIP call leg when the call is placed?

A.
show call active voice

B.
debug voip ipipgw

C.
show dialpeer voice

D.
debug voice dialpeer

Explanation:
The show call active voice command allows you to display the contents of the active
call table. The show call active voice command displays data from the plain old telephone service
(POTS) and VoIP call legs on the voice gateway. The information presented includes call times,
dial peers, connections, quality of service parameters, and gateway handling of jitter. This
information can be useful when you troubleshoot a range of voice quality problems.
